摘　　要：在分析过去地-气间相互作用的物理过程、研究进展基础上,探讨了土壤-植被-大气系统中水分与能量的传输过程在模型中不同的计算方法。同时对不同计算方法进行对比,确定了分析土壤-植被-大气系统中水分和能量传输方法的优缺点,提出了解决我国干旱地区土壤-植被-大气系统中水分和能量传输的一些思路,强调加强干旱地区观测资料积累,采用实测资料不断对不同分析计算进行验证,找出适用于西北干旱区的参数化方法,建立干旱区土壤-植物-大气模型。The paper reviewed research progress of water and energy physical process in interface between land and atmosphere and analyzed the different calculation methods of water and energy transfer in the SPAC （Soil-Plant-Atmosphere Continuity）. After comparing these different simulation methods, the paper gave out their advantages and disadvantages in applying to arid region. Some new ideas were proposed in resolving the water and energy transfer problem in soil-plant-atmosphere continuity in arid regions in China. Further study emphasizes on basic surface data collecting, and uses the field observation data to verify the accurate degree of different simulation method, so as to formulate the parameterized method and set up the simulation soil-plant-atmosphere continuity model suitable for arid Northwest China region.
